Sensor system for compensating information processing rate

Abstract

A sensor system mounted on a vehicle includes: a first sensor configured to acquire information on a first area outside the vehicle; a second sensor configured to acquire information on a second area that partially overlaps with the first area outside the vehicle; and a controller configured to change an information acquisition rate of the first sensor and an information acquisition rate of the second sensor, in which when the information acquisition rate of one of the first sensor and the second sensor falls below a predetermined value, the controller increases the information acquisition rate of the other sensor to be higher than the predetermined value.

What is claimed is: 
     
       1. A sensor system mounted on a vehicle, comprising:
 a first sensor configured to acquire information on a first area outside the vehicle; 
 a second sensor configured to acquire information on a second area that partially overlaps with the first area outside the vehicle; and 
 a controller configured to change an information acquisition rate of the first sensor and an information acquisition rate of the second sensor, 
 wherein, when the controller determines that an operation temperature of one of the first sensor and the second sensor exceeds a first predetermined value according to acquisition of the information, the controller lowers the information acquisition rate of the one of the first sensor and the second sensor to suppress a calorific value of the one of the first sensor and the second sensor, and 
 when the controller determines that the information acquisition rate of the one of the first sensor and the second sensor lowered by the controller falls below a second predetermined value while the information acquisition rate of the one of the first sensor and the second sensor is being lowered by the controller, the controller increases the information acquisition rate of the other one of the first sensor and the second sensor to be higher than the second predetermined value. 
 
     
     
       2. The sensor system according to  claim 1 , wherein the other one of the first sensor and the second sensor is a LiDAR sensor, and
 the controller increases the information acquisition rate of the other one of the first sensor and the second sensor by increasing the number of light sources that emit detection light. 
 
     
     
       3. The sensor system according to  claim 2 , wherein the one of the first sensor and the second sensor is a LiDAR sensor or a camera. 
     
     
       4. The sensor system according to  claim 1 , wherein the other one of the first sensor and the second sensor is a camera, and
 the controller increases the information acquisition rate of the other one of the first sensor and the second sensor by increasing a frame rate. 
 
     
     
       5. The sensor system according to  claim 4 , wherein the one of the first sensor and the second sensor is a LiDAR sensor or a camera. 
     
     
       6. The sensor system according to  claim 1 , wherein the one of the first sensor and the second sensor is a LiDAR sensor or a camera. 
     
     
       7. The sensor system according to  claim 1 , wherein the other one of the first sensor and the second sensor is a LiDAR sensor, and
 the controller increases the information acquisition rate of the other one of the first sensor and the second sensor by increasing a scanning frequency of detection light.
